The Robo-Sandvich is a promotional item equipped by the Heavy. The Genuine form of this item is obtained by opening a What's in the Sandvich Box?, which was given to San Diego Comic-Con 2012 attendants who purchased the 1:1 Sandvich toy made by ThreeA Toys. It appears as a robotic version of the Sandvich in the style of other Mann vs. Machine models.
- The Robo-Sandvich was added to the game.
- The "bite" bodygroup does not remove the original model, causing the bite model to clip into the regular model and rendering it twice.
